Super Geotextile
1. High strength tensile resistance: High quality materials and special processes endow it with tensile strength far exceeding that of ordinary geotextiles, which can withstand large tensile forces of soil and ensure the stability of engineering structures.
2. Strong puncture resistance: With special treatment or multi-layer design, it can resist sharp objects such as gravel and tree roots, extend its service life, and reduce maintenance costs.
3. Efficient drainage: The unique structure forms a smooth drainage channel with excellent permeability, which can quickly remove accumulated water and maintain the stability of the engineering structure.
4. Corrosion resistance and aging resistance: added with corrosion resistance components and treated with UV resistance, it can be used stably in complex environments for a long time and reduce the cost of the whole life cycle.
Products Introduction：
Super geotextile is a high-performance geosynthetic material made from high-strength fibers through advanced processes such as needle punching, thermal bonding, or weaving. Compared to traditional geotextiles, it adopts a special material formula and structural design, achieving comprehensive upgrades in mechanical properties, durability, and other aspects. Its appearance is smooth and uniform, with a tough texture, which can play a key role in various complex engineering environments and provide reliable guarantees for engineering construction.
Product Features：
1. High strength and toughness: Using high-quality high-strength fibers and special weaving techniques, super geotextiles are endowed with excellent tensile strength and tear resistance. When subjected to the tensile force generated by soil deformation, it is not easily broken or damaged, effectively enhancing soil stability.
2. Excellent puncture resistance: Through special surface treatment or multi-layer composite structure design, super geotextile has strong puncture resistance, which can resist the puncture of sharp objects such as gravel and tree roots, prevent local damage from affecting overall performance, and extend service life.
3. Efficient drainage performance: The unique three-dimensional pore structure forms a smooth drainage channel with excellent permeability. It can quickly discharge accumulated water in the soil, reduce pore water pressure, effectively avoid soil softening, settlement and other problems caused by accumulated water, and maintain the stability of the engineering structure.
4. Excellent corrosion resistance and aging resistance: the raw materials are added with special corrosion resistance components and treated with UV resistance, so that they can still maintain good physical properties and greatly reduce the cost of the whole life cycle in the chemical corrosive environment such as acid, alkali, salt, and the natural environment such as sunlight exposure and high and low temperature alternation.
5. Good construction convenience: Lightweight, flexible, easy to cut, transport, and lay, can greatly improve construction efficiency. At the same time, it has strong adhesion with the soil, can adapt to different terrains and engineering requirements, and reduces construction difficulty.
